The one memory I have that is imbedded in my mind is our 1st MFM. It was the 1st time she was shared.
I have fingered my wife thousands of times, I know her pussy better than my own face. I have often fingered her while I was fucking her, sliding my hand between us and rubbing her clit with my thumb. My wife can cum just on my cock but she claims her orgasm is more intense when I finger her at the same time.
So on the night of our 3sum we were all in bed together. After some time of us 2 men exploring her body she begs to be fucked. I went 1st, fucking her to an orgasm before pulling out and laying beside her. She rolls on her side facing me and asks if Mick could fuck her. I reply "if she wants him too". Her leg goes up and back over his hip and he is in her before I can change my mind.
My wife is facing me, kissing me as Mick fucks her. After playing with her tits a bit I slide my hand down to her clit and got the biggest shock of my life. I thought I knew how my wife's pussy felt but this time it felt completely different. 1 I could feel Mick's cock sliding inn and out. Even though I knew he was fucking her it was still a shock to feel my wife's pussy and find another cock in it but the real shock was how wide her pussy lips were spread. It could have been the different angle my hand was on using my finger instead of my thumb or it could be the fact that Mick was bigger than me or both but the sensation was intoxicating. It was that intoxicating I couldn't remove my hand, the way her outer lips were so separated leaving her pussy wide open and how her inner lips felt so stretched tight around his cock had me mesmerized. I fingered her clit until her body shivered in the most intense orgasm I had seen. Even after her orgasm I couldn't remove my hand, I left it there on her clit feeling his cock move inside my wife until it stopped and I felt his cock pulse as he came inside her.
To this day that was the most erotic moment of my life.
